Definitions

  • a filter system for the intake air of internal combustion engines is described.
  • An air filter is known from DE 197 56 247, this is used in particular for cleaning the air drawn in by an internal combustion engine.
  • the air filter essentially has one oval or Egyptian shape. This has the purpose of possibly penetrating water run better and improve airflow capacity.
  • a product separator is known from DE 196 18 198, which is used for solid particles to separate from a gas stream.
  • a filter cartridge is provided for this purpose the filter cartridge is arranged in a housing.
  • the housing also has a Baffle, which pursues the purpose of a part of the inflowing solid particles convey directly into a collecting container without loading the filter cartridge.
  • a disadvantage This so-called pre-separator is that only relatively large dirt particles be derived. Most of the dust and suspended matter gets onto the filter cartridge and leads to a rapid build-up of a filter cake, which the flow resistance can rise.
  • the invention is based on the object of avoiding the disadvantages mentioned and to create a filter system which has a high degree of separation and at the same time a long service life. Especially when used in agricultural machinery, commercial vehicles or other machines, a very high degree of separation is absolutely necessary. Nevertheless, the filter system required should have a small construction volume.
  • the main advantage of the invention is that the combination of an oval Filter element, which requires little space with a cyclone pre-separator enables a particularly compact design.
  • a secondary element is provided for the main filter element. This remains with the exchange of the main filter element on the clean air connection so that the introduction of Avoid dust or dirt in the clean air area when changing the main filter element becomes.
  • a further embodiment of the secondary element provides for a nonwoven material to be used use.
  • This fleece material has the advantage of providing good protection for the clean air area is guaranteed with a low flow resistance.
  • the main filter element is at the end facing the clean air nozzle provided with an external radial seal.
  • the Main filter element in the housing serves one arranged on the opposite side Compression spring on the one hand on the main filter element and on the other hand on one Supported housing cover.
  • Figure 1 shows a section through the filter.
  • Figure 2 is a plan view seen from the clean air side.
  • the filter system according to Figure 1 consists of a housing 10, which with a pivotable lid 11 can be closed.
  • a filter element 12 as the main filter element
  • a filter element 13 as the secondary element or safety filter.
  • the filter element 12 is on the left side end provided with a sealing element 14 and rests there on the housing.
  • On the right-hand side At the end, the filter element is supported on the cover 11 by a spring 15.
  • the Compression spring secures the filter element in the position shown here.
  • the Filter element 12 consists of a zigzag folded filter paper or filter fleece, which is held by two end plates 16, 17.
  • the unpurified and to be filtered Intake air initially flows into a pre-separator system 19 according to arrow 18.
  • This pre-separator system 19 consists of individual cyclone pre-separators, here here only one element is shown to represent a large number of cyclone pre-separators is.
  • This element has a swirl-producing guide element 20. Through this element 20 the inflowing raw air is rotated so that dust particles according to are flung outwards with the arrow 21 and reach a dust collection chamber 22 there and can be discharged via the dust discharge valve 23. Dievorgenahe Air flows upwards in the middle according to arrow 24 through a clean air opening 25 and further into the outer region 26 of the downstream filter system. When flowing through this air is retained by the filter element 12, The cleaned intake air enters the clean air area 27 and flows from there over the Clean air opening 28 to the internal combustion engine, not shown here.
  • FIG. 2 shows a plan view of the design of the housing 10 and thus the Filter element 12.
  • the housing 10 is essentially oval, the cover 11 pivotally connected to the housing 10 via the hinge 29.
  • the filter element 12 adapts to the oval contour of the housing 10 and therefore enables a very large effective filter area.
  • the cyclone area 19 extends almost over the entire Width of the oval housing 10 and thus allows a high air flow.
  • the Line 30 shown in broken lines represents the contour of the bonnet in FIG. 2 and also in FIG of the vehicle. It can be seen that the filter system adapts optimally to this Contour adjusts.
